実施例で得られた化合物5g、乳糖90g、トウモロコシデンプン34g、結晶セルロース20gおよびステアリン酸マグネシウム1gをブレンダーで混合した後、打錠機で打錠することにより、錠剤が得られる。
化合物の投与液は、0.5w/v%メチルセルロース溶液を用い、メノウ乳鉢で粉砕しながら1mg/mLの濃度になるように懸濁液を調製した。動物は、雄性C57/BL6Jマウス(日本チャールスリバー株式会社)を6週齢から8週齢で入荷し、9週齢から13週齢で使用した。試験日前日の17時から18時の間を目安に絶食を開始し、16時間から17時間程度の絶食下で試験を開始した。各群5匹ずつを用いた。尾静脈から採血を行った後、化合物懸濁液を10mg/kgとなるように経口投与した。陰性対照群には0.5w/v%メチルセルロース溶液を投与した。経口投与から25分後に尾静脈から採血を行い、経口投与から30分後に30w/v%グルコース溶液を10mL/kgで経口投与した。グルコース負荷から15分、30分、60分、120分後に尾静脈から採血を行った。採取した血液を遠心して血漿を分取し、Glucoroder-GXT(株式会社エイアンドティー)で血漿血糖値(mg/dL)を測定した。個体毎に、糖負荷5分前、糖負荷15分、30 分、60分、120分後の血糖値を用いてAUC(mg/dL・min)を算出した。群毎におけるAUC平均値を算出し、陰性対照群と比較したAUC低下率(%)を算出し、薬効の指標とした。
化合物を秤量し、0.5w/v%メチルセルロース中で1から10mg/mLの濃度になるように懸濁し、投与液を調製する。化合物の用量をふる場合は調製した投与液を0.5w/v%メチルセルロースを用いて順次希釈し、投与液を調製する。動物はZucker fatty ラット(日本チャールスリバー)、雄10-18週齢を使用する。試験の2日前に血糖値、体重、血中インスリン値を測定し、各パラメータが均等になるように各群n=5から8に割り付ける。試験実施日の前日15時頃に絶食を行う。試験当日、ラットに前述の方法によって調製される化合物投与液を1から5mL/kgの容量で経口投与し、その30分後に25~50w/v%グルコース溶液を4mL/kgの容量で経口投与する。採血は化合物投与前、グルコース投与5分前、グルコース投与30、60、120、180分後に、ラット尾静脈より行う。得られた血液を遠心した後、プラズマを分離し、プラズマ血糖値をGlucoroder-GXT(株式会社エイアンドティー)で測定する。各群におけるグルコース投与後の血糖値のAUCを算出し、vehicle投与群の血糖値AUCに対する低下率(%)を化合物の薬効として表記する。
